The Test Article Vehicle Transfer System (TAVTS) will demonstrate the transfer of vehicles between a surrogate Maritime Pre-positioning Force (Future) (MPF(F)) Mobile Landing Platform (MLP) ship and a side port platform on a large medium-speed roll-on/roll-off (LMSR) ship.

If the first movie with pirates was a real situation look at this :
I am so proud of this movie and you will see why. Panic and fear in the souls of sailors from the vessel is very high and they fight against pirates and defeat them. All respect for them. I want to say that the only weapons on the ship are water cannons.

After pouring hardener, the paint in use should be completely used. When the available life is past, the paint may harden inside the pot or it may clog the nozzle or hose. Even during a rest, the paint should be used so that no residuel paint is leftover; brushes and rollers should be washed roughly in thinner and then dipped in it. No problem is expected at any temperature if painting is carried out with one hour.
Never mix excessive thinner ( for undercoat within 10%; for top coat within 5%).
There are cases where no reaction takes place when the mixing ratio is innapropriate or the paint is insufficiently stirred. Use a special paint agitator. If a wood strip is used, without any other means, stir the paint sufficiently in the 4 corners and to blend upper and lower layers.
Carefully wash brushes and rollers in thinner up to the interior, or they cannot be used again. After being washed thoroughly, they may be dipped in thinner, fresh water or dried in the shade.
Any surface which is damp with moisture or contains salt content should not ahave paint applied to it, otherwise it will peel off, especially in the case conventional paints. Synthetic Resin paints are a little less affected.
In the case of airless spray painting, a dry film thickness of 300 to 400 microns is generally obtained. A thickness of about 100 microns can be obtained by brush painting. When painting by brush after scalling, it is necessary to aply several coats.
When this type of paint is applied over a synthetic resin paint coat, the undercoat may be dissolved. However, if the undercoat is more than 3 months old, there is no such possibility
This type of paint should never be used bby adding thinner after the available life is over.
When applying primers a few times, their color should be varied every time to eliminate the possibility of inadvertenly leaving out places unpainted.
The Douglas Sea Scale is a scale which measures the swell of the sea and the height of the waves:
- Degree 0—no measurable wave height calm sea
- Degree 1—waves >10 cm. rippled sea
- Degree 2—waves 10–50 cm. smooth sea
- Degree 3—waves 0.5–1.25 m. slight sea
- Degree 4—waves 1.25–2.5 m. moderate sea
- Degree 5—waves 2.5–4 m. rough sea
- Degree 6—waves 4–6 m. very rough sea
- Degree 7—waves 6–9 m. high sea
- Degree 8—waves 9–14 m. very high sea
- Degree 9—waves >14 m. phenomenal sea
Waves are primarily caused by the wind and its action on the surface of the water. Their height depends on how long the wind has been blowing and also on the strength of the wind. Waves formed by the wind blowing locally are termed "sea". Waves formed by the wind blowing at a distance from the place of observation are termed "swell".
Some waves result from earthquakes or underwater seaquakes and on approaching shallow water they become abnormally high and begin to break with great violence causing enormous devastation and loss of life. They are termed "tsunami" and we will all remember the tragic waves caused my a seaquake near Sumatra on Dec 26th, 2004, which claimed the lives of nearly 300,000 people in South-East Asia.
The following terms are frequently used in connection with waves:
- the length of a wave, that is the horizontal distance from crest to frest or trough to trough. If the distances between the crests of waves are far apart, the sea is termed "a long sea". When the crests are close together the sea is termed "a short sea", like for example in the Baltic Sea.
- the height of wave, that is the vertical distance from trough to crest.
- the period of a wave, that is the time between the passages of two successive wave crests or troughs past a fixed point.
- the velocity of a wave, that is the rate at which the crest travels.

The weather is the state of the atmosphere with refference to wind, temperature, state of the sea, cloudiness, precipitation, atmospheric pressure, humidity, mist, fog, ice conditions.
It is important for seaman to understand all phenomena conected with the weather and to be able to read weather maps and listen to the weather forecast and report weather conditions at sea such as visibility and the direction of wind and its force according Beaufort Wind Scale.
Winds
Winds are mainly caused by a difference of temperature which in turn is sometimes responsible for the differences of barometric pressure. The strength and speed of wind at any given time depend on the gradient of atmospheric pressure that is the rate at which pressure changes with distance.
Speed of movement of pressure systems
Slowly: Moving at less than 15 knots
Steadily: Moving at 15 to 25 knots
Rather quickly: Moving at 25 to 35 knots
Rapidly: Moving at 35 to 45 knots
Very rapidly: Moving at more than 45 knots
Timing of gale warnings
Imminent: Within 6 hours of time of issue
Soon: Within 6 - 12 hours of time of issue
Later: More than 12 hours from time of issue
Terms referring to wind:
Backing - Indicates the changing of wind in the anticlockwise direction (i.e. from W to SW)
Becoming cyclonic - Indicates that there will be considerable changes in wind direction across the path of a depression within the forecast area.
Wind direction - Indicates the direction from which the wind is blowing.
Veering - Indicates the changing of the wind in a clockwise direction (i.e. from SW to W)
Variable - Indicates the wind constantly changing the direction from which it blows.
